Vite Projects

For Vite projects, you can import styles in multiple ways:

// Method 1: Import CSS directly
import 'drag-puzzle-captcha/DragPuzzleCaptcha.css';

// Method 2: Import as style (alias)
import 'drag-puzzle-captcha/style';

// Method 3: Import in your CSS file
/* In your main CSS file */
@import 'drag-puzzle-captcha/DragPuzzleCaptcha.css';

Next.js Usage

import React, { useState } from 'react';
import dynamic from 'next/dynamic';
import 'drag-puzzle-captcha/DragPuzzleCaptcha.css';

// Dynamic import to avoid SSR issues
const DragPuzzleCaptcha = dynamic(
  () => import('drag-puzzle-captcha'),
  { ssr: false }
);

export default function MyPage() {
  const [isVerified, setIsVerified] = useState(false);

  return (
    <div>
      <h1>Secure Form</h1>
      <DragPuzzleCaptcha onVerify={setIsVerified} />
      {isVerified && <p>✅ Verified!</p>}
    </div>
  );
}

Modal Usage

import React, { useState } from 'react';
import DragPuzzleCaptcha from 'drag-puzzle-captcha';

  const [isVerified, setIsVerified] = useState(false);

  const handleVerification = (success) => {
    setIsVerified(success);
    if (success) {
      setShowCaptcha(false);
    }
  };

  return (
    <div>
      <button onClick={() => setShowCaptcha(true)}>
        Verify Identity
      </button>
      
      {showCaptcha && (
        <DragPuzzleCaptcha 
          showModal={true}
          onVerify={handleVerification}
          onCloseModal={() => setShowCaptcha(false)}
        />
      )}
    </div>
